Description

Pot lid with a sensor device

The present invention refers to a pot lid with a sensor device, in particular to a lid of a household pot, said sensor device being attached to said pot lid.

A pot lid with a sensor device is known and formed in a manner that a sensor device is incorporated into a handle of a household pot. However, there exists a continuous problem with the sealing of a sensor, particularly on the spatially curved lid, and as a result with the readout of the temperature and uniform rest of the probe against the surface of said lid, respectively. One of the known solutions comprises the attachment of the sensor device to the lid by means of the vacuum, which turned out to be inadequate since the vacuum releases due to the vibration of the molecules during the heating up. In addition, all sensors with the known solutions are incorporated into the lid handle in a non-removable manner.

It is the object of the present invention to create a pot lid with a sensor device which remedies drawbacks of the know solutions and can be arranged on all lid types, in particular onto the spatially curved lids of the household pots.

The object as set above is solved with characteristics as set forth in claim 1. Details of the invention can be obtained from subclaims. It is provided for, according to the present invention, that a bond between a sensor device and a pot lid is formed as a magnetic bond resulting in the sensor device to be easily attached to said lid when the latter is made of magnetic material. When, however, said lid is made of non-magnetic material, such as glass for instance, a ring shaped interface of magnetic material is arranged on said lid at the side thereof averted from said pot in order to create a magnetic bond with the sensor device, said interface being intended to cooperate with said sensor device. The invention is further described in detail by way of non-limiting preferred embodiment, and with a reference to the accompanying drawing, where

Fig. 1 shows a three-dimensional exploded view of a household pot with a sensor device according to the invention,

Fig. 2 shows a longitudinal cross-sectional view of a sensor device of Fig. 1. Fig. 1 shows a lid 1 of a household pot 2, said lid 1 being formed either of magnetic material, such as steel for example, either of non-magnetic material, such as glass, plastic and similar, for example. In the embodiment shown said lid 1 is formed as a spatially curved glass surface 3, a thin-walled cup for instance, a handle 4 being arranged at the apex thereof in order to manipulate with said lid. Spaced from said handle 4, a ring-shaped interface 5 is arranged on said surface 3, in essence on the side of the surface 3 averted from said pot 2, said interface 5 being bonded by means of an adhesive layer 6 to said surface 3. A sensor device 7 being removable attached to said interface 5 which is preferably made of magnetic material.

Fig. 2 shows a cross-sectional view of said sensor device 7 which is via said ring-shaped interface 5 removable attached to said pot lid 2. According to the invention, said demountable connection between said interface 5 and said device 7 is preferably formed as a magnetic bond. Therefore, an insertion 9 being arranged in the body 8 of the sensor device 7, said insertion 9 embodying at least one permanent magnet, preferably two permanent magnets 10, 11. Said magnets 10, 11 are mutually spaced in said insertion 9 and arranged in a manner that the polarity thereof is reversed; it means that, when viewed in direction perpendicular to said surface 3 of the lid 1, the poles of the first magnet 10 are oriented in direction N-S whereas the poles of the second magnet 11 are oriented in direction S-N. Furthermore, said insertion 9 is formed with a centric through-hole 12 extending between said magnets 10, 11, a probe 13 protected with a sealing cover 14 being arranged in said hole 12. Said insertion 9 is further formed on the side facing said surface 3 of the lid 1 with a ring-shaped depression 15 intended to cooperate with said interface 5. Said sealing cover 14 is formed on the side thereof facing said surface 3 of the lid 1 with a radially extending flange 16 which, with the sensor device 7 according to the invention being fitted, sealingly abuts against said surface 3 of the lid 1. It is provided for, according to the present invention, that the depth of said depression 15 in said insertion 9 is greater than the entire thickness of the interface 5 and the layer 6 so that the latter two are entirely located within said depression 15 when the sensor device 7 according to the invention is fitted. In order to achieve that condition, an elastic deformation of certain parts of the sensor device 7 according to the invention is required during installation thereof.

Preferably, it is provided for according to the present invention that said sealing cover 14 is formed of elastic material, such as silicone rubber for instance, so that it is capable of being elastically deformed when pressed against said surface 3 during installation of the sensor device 7 onto the lid 1. Simultaneously with said elastic deformation of the sealing cover 14 said probe 13 is displaced in the axial direction of the body 8 of the sensor device 7, thus, accommodating easily to the curvature of each lid 1 used and still pressing securely against the surface 3 of the lid 1 reading the required parameters during operation. In addition, said body 8 is provided at the side thereof facing said surface 3 of the lid 1 with a circumferentially extending elastic ring 17 intended to cooperate with said surface 3. At the location of the cooperation with said surface 3, said elastic ring 17 is provided over the entire circumference thereof with an elastic lip 18 extending both in longitudinal direction of said body 8 and in the direction toward said surface 3. When installing sensor device 7 according to the invention onto said lid 1 and said surface 3, respectively, said lip 18 is deformed likewise, contributing additionally to the sealing of said sensor device 7 against the lid 1.

While the foregoing written description enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific exemplary embodiment herein. The invention should therefore not be limited by the above described embodiment, but by all embodiments within the scope and spirit of the invention as claimed.
